I did some math, and calculated that Webb's mirror would have to be 2000
times wider in order to get chorizo-level detail of Proxima Centauri at
Webb's shortest wavelength.  Longer wavelengths would require an even
larger mirror.

(Webb's resolution at 2 micron infrared is 0.1 arc seconds, and Proxima
Centauri spans 0.001 arc seconds at 4.2 light years.)
